For a .pdf of the below schematic for the R90S, R60S, R75/6, R90/6;  Click HERE

JUST BELOW is the same schematic as above but in large .GIF format.  Larry Simko provided me the original artwork for the below sketch, for which I thank him, and I have left his name at the bottom.     It should be expanded in your computer's imaging program as needed in order to see the fine details.    If you do not know how to do that, then use the above clickable .pdf version

Note that both the .GIF and the .PDF schematics have the corrected instrument cluster wiring diagram (some old BMW literature is wrong); and, that sometime in 1976, the wiring changed again, in some minor areas.

***near the bottom of this page is a HUGE .bmp version, very high resolution and detail

Here is the same thing, but in high resolution .bmp format; scan down!:
